Zim Gar (or ZimGar) is the brand, so if you google that it might help. There's some stuff out there, but it looks like it was a NY company importing Japanese guitars (and drums? Lots of drum info for some reason).

Saw the zimgar but thought it was just something put there by a kid. Called the guy to tell him what it was and he said he's sticking at $400. Unless he finds a sucker, he's going to have that for a LONG time.
Thanks for the input folks.

I lost out on a single-pickup version of this today because I got distracted and forgot to monitor the eBay auction. RBS started a thread on a similar bass a few days ago.

This bass, with no issues, in 2014, I would say might be worth $150. $400? No way!

Most folks would say this is a Teisco, but there is some speculation that this particular type of Teisco was made by Kawai. These instruments saw their highest profile in the
mid-sixties; seventies gets us into the lawsuit era instruments.

Let's just agree to identify all such instruments as these as "badged" Japanese basses. I have a bass identical to this one in every way, except where this bass says Zim Gar
mine says Encore.

I had an identical bass- gave it to a bud as it had a broken headstock(you could see thought the crack/split). It was actually playable- just barely- but I was afraid to touch the neck or HS for fear it would disintegrate. Beyond that, it seemed poorly constructed. I don't mind a cheapo as long as it plays fairly well, but this one was nothing special
